Mindstorms 3.0 Wish List —Jordan Bradford

I'm giving a presentation about Mindstorms on Wednesday. I have a slide near the end that talks about all the stuff I know people want to see added. Here's what I have so far: RCX === RC communication (but keep the IR port, too) more I/O ports (...)

Re: Mindstorms 3.0 Wish List —Mark Tarrabain

What I'd like to see is MUCH more elaborate expansion capability fot a completely new RCX paradigm. Using something like, say, pcmcia-ish cards to add new capabilities to the unit as desired. One card might add a dozen sensor inputs, while another (...) (21 years ago, 3-Nov-03, to lugnet.robotics)

Re: Mindstorms 3.0 Wish List —Jason J. Railton

Re: Mindstorms 3.0 Wish List —Thomas Garrison

More Speed? Re: Mindstorms 3.0 Wish List —Steve Hassenplug

(...) I can see the need for more I/O from the RCX, but I really don't understand why everyone thinks it needs more memory and CPU speed. I'm interested to hear about any projects that people have attempted which required more of either. Steve (21 years ago, 5-Nov-03, to lugnet.robotics, FTX)

Re: More Speed? Re: Mindstorms 3.0 Wish List —John Barnes

(...) I like using NQC because of the simplicity of downloading byte code based programs onto the Lego firmware environment. Using NQC, the CPU would need to be at least 10x to 100x faster to run the kind of programs I would like to run at an (...) (21 years ago, 5-Nov-03, to lugnet.robotics, FTX)

Re: More Speed? Re: Mindstorms 3.0 Wish List —Chris Phillips

Re: More Speed? Re: Mindstorms 3.0 Wish List —Chris Phillips

Re: More Speed? Re: Mindstorms 3.0 Wish List —Steve Hassenplug

Re: More Speed? Re: Mindstorms 3.0 Wish List —Mark Tarrabain

Re: More Speed? Re: Mindstorms 3.0 Wish List —Jordan Bradford

(...) I believe that is exactly what legOS does. It compiles your program and stores it in the firmware area. legOS has no firmware, and it ignores the ROM code, too. It accesses all the hardware directly. That's my understanding, at least. (21 years ago, 5-Nov-03, to lugnet.robotics)

Re: More Speed? Re: Mindstorms 3.0 Wish List —Chris Phillips

(...) Your understanding is correct. So why doesn't everybody use BrickOS? There are at least two reasons that I am aware of: 1. Many people, especially "non-programmers" find a full-blown C++ implementation to be intimidating and non-user-friendly. (...) (21 years ago, 5-Nov-03, to lugnet.robotics)

Re: More Speed? Re: Mindstorms 3.0 Wish List —Juergen Stuber

(...) Lejos is notoriously short on memory, with a half decent communication stack the RCX is full. In general I'd say with more memory and speed you can program more "high-level", and build more intelligent robots. As for a new RCX version I'd say (...)

Re: Mindstorms 3.0 Wish List —Jonathan Wilson

Re: Mindstorms 3.0 Wish List —Mike Reddy

(...) It does sometimes, but shielding in the unit does disrupt the signal. I would like the battery compartment to be separated from the CPU box, so we can distribute the weight and have two smaller boxes. That way, my designs don't need to allow (...) (21 years ago, 4-Nov-03, to lugnet.robotics)

Re: Mindstorms 3.0 Wish List —Paul Kleniewski

maybe sensors could have its own battery (watch like) and blue tooth connection with its rcx all problems with separation would be solved via configuration cause i think all sensors could be addressed separately so even somo robots could work (...) (21 years ago, 5-Nov-03, to lugnet.robotics)

Re: Mindstorms 3.0 Wish List —Rand Krakora

What they need to do is make it like a PDA with a compact flash slot. Then you could expand as needed. You could connect two controllers to communicate via 802.11 or bluetooth, etc. Or a CPU with CAN? It would be fairly cheap. Connect everything (...) (21 years ago, 4-Nov-03, to lugnet.robotics)

Re: Mindstorms 3.0 Wish List —Chris Phillips

Re: Mindstorms 3.0 Wish List —Steve Baker

(...) I agree - it's basically a good idea - but it's probably too expensive. (...) Using bluetooth for communications between RCX's - or between RCX and PC - is a bit of a non-starter, the range of bluetooth is intentionally rather short. An 802.11 (...)

Re: Mindstorms 3.0 Wish List —Brass Tilde

Re: Mindstorms 3.0 Wish List —John Gerlach
